FIELD

The present disclosure relates generally to human-computer interaction. More particularly, the present disclosure relates to identifying three-dimensional-human-gesture input.

BACKGROUND

Computing devices (e.g., smartphones, and/or the like) can provide (e.g., display on a display screen, and/or the like) a user interface that enables the computing device to interact with a user, including, for example, receipt of commands from the user, providing (e.g., displaying, and/or the like) information to the user, and/or the like. Some computing devices allow for gesture based inputs. Such devices can detect a gesture and provide an appropriate response. Traditional gesture-recognition techniques are complex and may be ineffective at recognizing gestures in situations where variability may exist. For example, such systems may have difficulty detecting gestures from different users, from different viewpoints, due to external conditions, and/or the like.

DETAILED DESCRIPTION

Example aspects of the present disclosure are directed to identifying three-dimensional-human-gesture input. For example, one or more computing devices can receive (e.g., from one or more sensors, and/or the like), data (e.g., three-dimensional data, and/or the like) describing one or more three-dimensional motions (e.g., of a user, object manipulated by such user, and/or the like) comprising a three-dimensional-human-gesture input. Based at least in part on the data describing the three-dimensional motion(s), the computing device(s) can generate two-dimensional data at least partially describing at least one motion of the three-dimensional motion(s). For example, in some embodiments, the computing device(s) can project a representation of at least a portion of the data describing the three-dimensional motion(s) onto a two-dimensional plane defined by each dimension of the two-dimensional data. Based at least in part on the two-dimensional data, the computing device(s) can identify the three-dimensional-human-gesture input.

The technology described herein can provide a number of technical effects and benefits, particularly in the area of computer technology. For example, the technology described herein can enable three-dimensional human-based inputs to be interpreted by computer systems using less complex two-dimensional-input-recognition techniques. The technology can provide for a conversion of three-dimensional input data to two-dimensional data that can be readily interpreted by computing systems. In this manner, suitable computing devices can be configured to interpret three-dimensional input data using two-dimensional recognition techniques. Additionally, the use of sensors that generate three-dimensional data can enable accurate detections of movements in three-dimensional space. Moreover, converting such data to two-dimensional data prior to gesture recognition can enable a processor to more accurately and easily interpret input data. Additionally, the technology described herein may enable certain computing devices that might otherwise been unable to do so (e.g., due to limited resources, and/or the like) to interpret three-dimensional human-based inputs within an appropriate response time, and/or the like.

With reference now to the Figures, example embodiments of the present disclosure will be discussed in further detail.

FIG. 1 depicts an example computing environment according to example embodiments of the present disclosure.

Referring to FIG. 1 , environment 100 can include one or more computing devices (e.g., one or more desktop computers, laptop computers, tablet computers, mobile devices, smartphones, servers, appliances, wearable devices, personal digital assistants, Internet of Things (IoT) devices, peripherals, user-input devices, and/or the like). For example, environment 100 can include computing devices 10, 20, 30, 40, 50, 60, and/or 70. In some embodiments, computing devices 10, 20, 30, 40, 50, 60, and/or 70 can be physically distinct from one another. Environment 100 can also include one or more networks 102 (e.g., one or more wired networks, wireless networks, and/or the like). Network(s) 102 can interface computing devices 10, 20, 30, 40, 50, 60, and/or 70 with one another.

Computing device 10 can include circuitry 104, which can comprise one or more processor(s) 106, one or more sensors 108, one or more communication interfaces 110, and memory 112 (e.g., one or more hardware components for storing executable instructions, data, and/or the like). Sensor(s) 108 can be configured to identify, describe, indicate, perceive, determine, and/or the like one or more variables, conditions, parameters, and/or the like of an environment of computing device 10. For example, sensor(s) 108 can include one or more global positioning system (GPS) receivers, wireless-network interfaces, altimeters, proximity sensors, ambient-light sensors, accelerometers, gyroscopes, compasses, barometers, cameras, inertial measurement unit (IMU) sensors, ultrasound sensors, radar sensors, and/or the like. Communication interface(s) 110 can enable computing device 10 to communicate with computing devices 20, 30, 40, 50, 60, and/or 70. Memory 112 can include (e.g., store, and/or the like) instructions 114. When executed by processor(s) 106, instructions 114 can cause computing device 10 to perform one or more operations, functions, and/or the like described herein. It will be appreciated that computing devices 20, 30, 40, 50, 60, and/or 70 can include one or more of the components described above with respect to computing device 10.

Unless explicitly indicated otherwise, the operations, functions, and/or the like described herein can be performed by computing devices 10, 20, 30, 40, 50, 60, and/or 70 (e.g., by one of computing devices 10, 20, 30, 40, 50, 60, or 70, by a combination of one or more of computing devices 10, 20, 30, 40, 50, 60, and/or 70, and/or the like).

FIGS. 2A-D depict example event sequences according to example embodiments of the present disclosure.

Referring to FIG. 2A, at (202), a user can be prompted to provide one or more three-dimensional-human-gesture inputs. For example, at (202A), computing device 10 can prompt a user of computing devices 10, 20, 30, 40, 50, 60, and/or 70 to provide one or more three-dimensional-human-gesture inputs. Additionally or alternatively, at (202B), computing device 20 can prompt the user of computing devices 10, 20, 30, 40, 50, 60, and/or 70 to provide one or more three-dimensional-human-gesture inputs.

For example, FIG. 3 depicts an example scene according to example embodiments of the present disclosure. Referring to FIG. 3 , scene 300 can include objects 302 and/or 304. A user can utilize object 302 (e.g., the user's hand, and/or the like) to hold object 304 (e.g., a magic wand, and/or the like). Object 304 can include computing device 20. Scene 300 can also include computing device 10. Computing device 10 can include sensors 108A, 108B, and/or 108C, which can, for example, be configured to monitor, track, and/or the like movements, positions, and/or the like of objects 302 and/or 304. Computing device 10 can include display device 310 for presenting one or more graphical interfaces for viewing by the user.

In some embodiments, the user can be prompted by computing device 10 to provide the three-dimensional-human-gesture input(s). For example, computing device 10 can generate data describing one or more graphical interfaces including one or more elements prompting the user to provide the three-dimensional-human-gesture input(s) and can communicate such data to display device 310, which can render the graphical interface(s) for viewing by the user, and/or the like. Additionally or alternatively, the user can be prompted by computing device 20 to provide the three-dimensional-human-gesture input(s). For example, computing device 20 can generate motion of object 304 (e.g., haptic feedback, and/or the like), which can prompt the user to provide the three-dimensional-human-gesture input(s).

The user can be prompted, for example, to provide one or more three-dimensional-human-gesture inputs characterized by manipulating, moving, repositioning, tilting, and/or the like object 304 (e.g., the tip of the wand, and/or the like) in accordance with trajectory 308 (e.g., from position 306A to position 306B, from position 306B to position 306C, and/or the like).

Returning to FIG. 2A, at (204), data describing one or more inputs to computing devices 10 and/or 20 can be received. The data can include data describing one or more three-dimensional motions (e.g., x coordinates, y coordinates, z coordinates, corresponding time stamps, and/or the like) comprising the three-dimensional-human-gesture input(s) (e.g., characterized by manipulating, moving, repositioning, tilting, and/or the like object 304 in accordance with trajectory 308, and/or the like). For example, at (204A), computing device 10 can receive data from sensors 108A, 108B, and/or 108C (e.g., one or more cameras, and/or the like) describing one or more three-dimensional motions of scene 300 (e.g., with respect to objects 302, 304, and/or the like) comprising the three-dimensional-human-gesture input(s). Additionally or alternatively, at (204B), computing device 20 can receive data from one or more sensors of computing device 20 (e.g., one or more IMU sensors, and/or the like) describing one or more three-dimensional motions of scene 300 (e.g., with respect to object 304, and/or the like) comprising the three-dimensional-human-gesture input(s). For example, the user (e.g., in response to the prompt(s), and/or the like) can have taken one or more actions (e.g., characterized by manipulating, moving, repositioning, tilting, and/or the like object 304 in accordance with trajectory 308, and/or the like) corresponding to the three-dimensional-human-gesture input(s), and computing devices 10 and/or 20 can receive data describing the three-dimensional motion(s) of scene 300, which can include the action(s) of the user.

At (206), computing device 10 can communicate (e.g., via network(s) 102, and/or the like) the data describing the three-dimensional motion(s) of scene 300 (e.g., the data received at (204A), and/or the like) to computing device 20. Similarly, at (208), computing device 20 can communicate (e.g., via network(s) 102, and/or the like) the data describing the three-dimensional motion(s) of scene 300 (e.g., the data received at (204B), and/or the like) to computing device 10. At (210), data describing the three-dimensional motion(s) can be received. For example, at (210A), computing device 10 can receive the data describing the three-dimensional motion(s) of scene 300 from computing device 20. Additionally or alternatively, at (210B), computing device 20 can receive the data describing the three-dimensional motion(s) of scene 300 from computing device 10.

At (212), two-dimensional data (e.g., x coordinates, y coordinates, corresponding time stamps, and/or the like) at least partially describing the three-dimensional motion(s) can be generated. For example, at (212A), computing device 10 can generate, for example, based at least in part on the data describing the three-dimensional motion(s) of scene 300 (e.g., the data received at (204A), (210A), and/or the like), two-dimensional data at least partially describing the three-dimensional motion(s) of scene 300. Additionally or alternatively, at (212B), computing device 20 can generate, for example, based at least in part on the data describing the three-dimensional motion(s) of scene 300 (e.g., the data received at (204B), (210B), and/or the like), two-dimensional data at least partially describing the three-dimensional motion(s) of scene 300. In some embodiments, generating the two-dimensional data can include projecting a representation of at least a portion of the data describing the three-dimensional motion(s) onto a two-dimensional plane defined by each dimension of the two-dimensional data.

At (214), computing device 10 can communicate (e.g., via network(s) 102, and/or the like) the two-dimensional data at least partially describing the three-dimensional motion(s) of scene 300 (e.g., the data generated at (212A), and/or the like) to computing device 20. Similarly, at (216), computing device 20 can communicate (e.g., via network(s) 102, and/or the like) the two-dimensional data at least partially describing the three-dimensional motion(s) of scene 300 (e.g., the data generated at (212B), and/or the like) to computing device 10.

At (218), computing device 10 can display one or more graphical interfaces comprising one or more elements depicting a representation of at least a portion of the data describing the three-dimensional motion(s) of scene 300. For example, referring to FIG. 3 , computing device 10 can generate data describing one or more graphical interfaces 312 and can communicate such data to display device 310 for viewing by the user. Graphical interface(s) 312 can include one or more elements 314 depicting a representation of at least a portion of the data describing the three-dimensional motion(s) of scene 300. For example, as indicated above, in some embodiments, generating the two-dimensional data can include projecting a representation of at least a portion of the data describing the three-dimensional motion(s) onto a two-dimensional plane defined by each dimension of the two-dimensional data. In some of such embodiments, element(s) 314 can depict such a representation (e.g., a two-dimensional rendering of trajectory 308, and/or the like).

Returning to FIG. 2A, at (220), one or more objects included in the three-dimensional motion(s) can be identified. For example, at (220A), computing device 10 can identify, for example, based at least in part on the data describing the three-dimensional motion(s) of scene 300 (e.g., the data received at (204A), (204B), and/or the like), objects 302 and/or 304 within the three-dimensional motion(s) of scene 300. Additionally or alternatively, at (220B), computing device 20 can identify, for example, based at least in part on the data describing the three-dimensional motion(s) of scene 300 (e.g., the data received at (204A), (204B), and/or the like), objects 302 and/or 304 within the three-dimensional motion(s) of scene 300. In some embodiments, such object(s) can be identified from amongst a plurality of different predefined, distinct objects associated with a plurality of different predefined, distinct three-dimensional-human-gesture inputs.

At (222), the three-dimensional-human-gesture input(s) can be identified based at least in part on the two-dimensional data. For example, at (222A), computing device 10 can identify the three-dimensional-human-gesture input(s) (e.g., characterized by manipulating, moving, repositioning, tilting, and/or the like object 304 in accordance with trajectory 308, and/or the like) based at least in part on the two-dimensional data generated at (212A), (212B), and/or the like. Additionally or alternatively, at (222B), computing device 20 can identify the three-dimensional-human-gesture input(s) (e.g., characterized by manipulating, moving, repositioning, tilting, and/or the like object 304 in accordance with trajectory 308, and/or the like) based at least in part on the two-dimensional data generated at (212A), (212B), and/or the like.

In some embodiments, computing devices 10 and/or 20 can store data describing a plurality of different predefined, distinct three-dimensional-human-gesture inputs. Such data can include, for each particular three-dimensional-human-gesture input of the plurality of different predefined, distinct three-dimensional-human-gesture inputs, two-dimensional data describing one or more three-dimensional motions associated with the particular three-dimensional-human-gesture input. In some of such embodiments, computing devices 10 and/or 20 can identify the three-dimensional-human-gesture input(s) from amongst the plurality of different predefined, distinct three-dimensional-human-gesture inputs based at least in part on a correspondence between: at least a portion of the two-dimensional data at least partially describing the three-dimensional motion(s), and at least a portion of the data describing the plurality of different predefined, distinct three-dimensional-human-gesture inputs. In some embodiments, the portion of the data describing the plurality of different predefined, distinct three-dimensional-human-gesture inputs can be identified based at least in part on the identified object(s) included in the three-dimensional motion(s) (e.g., a search for corresponding data can be narrowed to data describing inputs associated with such object(s), and/or the like). In some embodiments, identifying the three-dimensional-human-gesture input(s) can include utilizing one or more two-dimensional-movement-recognition models (e.g., stroke-recognition algorithms, character-recognition algorithms, handwriting-recognition algorithms, and/or the like) to analyze at least a portion of the two-dimensional data (e.g., to identify one or more two-dimensional movements corresponding to the three-dimensional-human-gesture input(s), and/or the like). In some of such embodiments, one or more of such two-dimensional-movement-recognition model(s) can be preexisting (e.g., need not be reconfigured to identify the two-dimensional movement(s), and/or the like).

Responsive to identifying the three-dimensional-human-gesture input(s), at (224), one or more functions associated with the three-dimensional-human-gesture input(s) can be identified and invoked. For example, the three-dimensional-human-gesture input(s) (e.g., characterized by manipulating, moving, repositioning, tilting, and/or the like object 304 in accordance with trajectory 308, and/or the like) can be associated with one or more functions (e.g., casting a spell, and/or the like), for example, associated with an application (e.g., a game, and/or the like), and responsive to identifying the input(s), at (224A), computing device 10 can identify and invoke the associated function(s). Additionally or alternatively, responsive to identifying the input(s), at (224B), computing device 20 can identify and invoke the associated function(s).

FIG. 4 depicts an example scene according to example embodiments of the present disclosure. Referring to FIG. 4 , scene 400 can include object 402 (e.g., a coffee cup, and/or the like). Object 402 can include computing device 30. Scene 400 can also include computing devices 10, 40, and/or 50. Computing devices 10, 30, 40, and/or 50 can be of different types (e.g., computing device 30 can be a computing device comprising an IMU sensor embedded in a coffee cup, computing device 40 can be an audio-controlled personal-assistant device, computing device 50 can be a smart-appliance coffee maker, and/or the like). Computing device 40 can include sensor 406 (e.g., a microphone, and/or the like).

For example, a three-dimensional-human-gesture input (e.g., associated with lifting a coffee cup, and/or the like) can be characterized by manipulating, moving, repositioning, tilting, and/or the like object 402 from position 404A to position 404B, and/or the like. Additionally or alternatively, a different three-dimensional-human-gesture input (e.g., associated with an empty coffee cup, and/or the like) can be characterized by manipulating, moving, repositioning, tilting, and/or the like object 402 from position 404C to position 404D, and/or the like.

The three-dimensional-human-gesture input (e.g., associated with lifting the coffee cup, and/or the like) characterized by manipulating, moving, repositioning, tilting, and/or the like object 402 from position 404A to position 404B, and/or the like can be associated with a function of computing device 40 (e.g., signaling the user has begun their morning routine, it is time for computing device 40 to read aloud the latest news updates, and/or the like). Similarly, the three-dimensional-human-gesture input (e.g., associated with an empty coffee cup, and/or the like) characterized by manipulating, moving, repositioning, tilting, and/or the like object 402 from position 404C to position 404D, and/or the like can be associated with a function of computing device 50 (e.g., signaling the user may desire additional coffee, computing device 50 should utilize sensor 408 to determine whether it should brew additional coffee, and/or the like).

For example, at (226A), computing device 10 can receive data from sensors 108A, 108B, and/or 108C (e.g., one or more cameras, and/or the like) describing one or more three-dimensional motions of scene 400 (e.g., with respect to object 402, and/or the like) comprising the three-dimensional-human-gesture input(s). Additionally or alternatively, at (226B), computing device 30 can receive data from one or more sensors of computing device 30 (e.g., one or more IMU sensors, and/or the like) describing one or more three-dimensional motions of scene 400 (e.g., with respect to object 402, and/or the like) comprising the three-dimensional-human-gesture input(s).
